Kitchen waste treatment method

Abstract

The invention discloses a kitchen waste decomposition method. The method comprises the following steps of: 1, preparation of a microbial inoculum: selecting a single microbial inoculum or a complex microbial inoculum of aspergillus niger, trichoderma harzianum, saccharomycetes, bacillus subtilis, bacillus licheniformis and nitrifying bacteria with high activity of nitrifying enzyme, protease and cellulase as a fermentation microbial inoculum; 2, microbial inoculum activation: fully mixing flour and water according to a mass ratio of 1: (10-12), heating, gelatinizing, cooling to room temperature, adding the fermentation microbial inoculum accounting for 1%-2% of the mass of the paste, and activating at room temperature for 2-5 hours; 3, fermentation: mixing the kitchen waste with a proper amount of activating microbial inoculum, and then adding the mixture into a fermentation vat for fermentation; 4, collection and utilization of fermentation liquor: using the fermentation liquor as a foliar fertilizer or a water-soluble fertilizer of flowers and plants; and 5, residue treatment and utilization: mixing residues and a proper amount of soil and using the mixture as a flower and plant substrate. According to the method, the kitchen waste generated at home is treated, and the pollution caused by the kitchen waste to the environment can be solved from the source.

Description

Technical field [0001] The present invention relates to the field of waste treatment, and more particularly to a kitchen waste treatment method. Background technique [0002] The kitchen garbage is mainly composed of leftovers, leftovers, rotten leaves, etc., has a nutritious, very easy to rot, and the kitchen garbage is generally in plastic bags. Although my country advocates garbage classification, people are throwing a restaurant At the time, few people were classified by the kitchen garbage with plastic bags, which caused the labor intensity of the garbage disposal enterprise sorting workers, and the cost of food waste treatment was increased, and the mosquito, spreading the disease due to the nutrition of kitchen waste. It brings a threat to the health of garbage sorters, making this good policy of this profit, it is difficult to implement. [0003] At present, there are many methods for kitchen waste treatment, such as: Germany uses a continuous fermentation method to handl...

AI Technical Summary

Problems solved by technology

In some places in my country, a screw extruder is used to extrude the juice from the kitchen waste, and the residue is inoculated for fermentation. The juice is first subjected to aerobic fermentation and then anaerobic fermentation in a large fermentation tank. The cost of treatment is very high, and the gain outweighs the gain

There are also some places where a pond is dug underground for processing. After fermentation, the juice and residue are separated, which is labor-intensive and completely a face-saving project.

In some places, landfill is used to dispose of domestic waste, polluting groundwater sources
